Australia and China's sunglasses standard variance analysis
As the production and import and export of sunglasses for the first big country, our country has international competitiveness in the industry of sunglasses.
As far as I am;
China customs statistics show that 2006-1
In September, sunglass export amount is 6.
600 million dollars.
Glasses export market in our country are mainly concentrated in Hong Kong, China, the European Union, the United States, Japan and other developed countries or regions, the above countries and regions account for 70% of total exports, accounting for 30% of the total in other countries and regions.
However, export to Australia and New Zealand sunglasses accounts for only 8% of the total, the main reason is that the trade technical barriers -
Sunglasses Australia standard, it has to do with sunglasses standards exist obvious differences in our country, the problems worthy of attention.
As is known to all, China's current standard of effective sunglasses is the QB2457 -
1999, it is not equivalent in U. S. standard ANSI280.
And 86 'over-the-counter factory glasses sunglasses and decorative requirements.
Sunglasses Australia standard refers to the AS/NZS 1067:2003 'Sunglassesand fashion' doubtful ', dumb Australian and New Zealand not by eu standards, standardization of Australia to fulfill the provisions of the WTO/TBT, adhere to the open, the principle of independence, appropriate process and consensus, so sunglasses Australia standard (
Hereinafter referred to as the Australia standard)
With the national standard of sunglasses (the
Hereinafter referred to as the national standard)
Have the following differences: 1.
Standards define the scope of different Australian standard: plain sunglasses, top coke for O.
OOD lens (
, resistance to the sun radiation, suitable for drivers, children's sunglasses lens;
Not applicable to safety goggles, tanning goggles, ski goggles.
Gb: suitable for sunshade lens, light color sunglasses and special to use f skiing, beach, mountain climbing, etc. , sunglasses.
Do not apply to the artificial light radiation shield goggles and vision correction with glasses.
Sunglasses for different spectral range (
With blue light project requirement in Australia standard, national standard of no such requirements.
In the Australian standard points out: the sun blue light transmittance (
: in the m - sea level atmospheric quality
2 solar radiation spectral distribution under the condition of Es (
Risk and blu-ray function B (
Weighted factors, wavelength average between 400 nm to 500 nm.
Australian standard stipulated in the blu-ray absorption: when the lens express its blu-ray absorption rate is X %, blue light transmittance is the sun rSB should be no (or
One X 5)
Blue light transmittance: when the lens express their blue light transmittance is less than X %, blue light transmittance is the sun rSB should be no (or
Because the sun has a very high brightness and spectrum, and contains rich in blue light, when visible blue wavelengths in the spectral range for 415 nm to 490 nm, it causes damage to the retina may be more likely than other light waves, at the same time, the sun's rays on the horizon but not more than safe exposure generally limit.
Illumination on the snow, for example, the blue part is dangerous, not directly.
With Q in Australia standard, national standard, no such symbols in Q is relatively visual attenuation factor, Q = Rsig/rv, Rsig spectral power distribution of traffic signal lamp is sun glasses, light transmittance;
The rv is the standard D65 light body is light of the sun light transmittance of the lens.
For example: if the rv = 95%, Q = O.
80,rsig = ?
Because the Q = rsig/rv rsig = 76%.
Different ultraviolet spectral range: Australian standard UVB ultraviolet spectrum (
280 nm～315 nm)
V, gb UVB (
290 m～315 m)
5 the rv or 30% or less;
Australia the ultraviolet spectrum of UVB (
315 nm 400 nm)
The rv, or less gb ultraviolet spectrum UVA (
315 nm～380 nm)
Australia with ultraviolet spectrum UVB (
315 nm～350 nm)
Band, and is now standard without the band requirement.
